Trophic level pyramid: - Producers: These are organisms that produce their own food through photosynthesis, such as plants and algae. They form the base of the trophic pyramid and provide energy for all other organisms in the ecosystem. Example: grass. - Primary Show more…

1) Name the trophic levels represented in the food web. 2) The energy flow through ecosystems can be viewed as a pyramid. Draw a step-pyramid of energy for the ecosystem above, with each step (tier) representing the energy contained in each trophic level. How does energy change with trophic level? Why? 3) Trophic-level transfer efficiency ranges from about 5-20% in different ecosystems, but is it low?

Leuning Tasks 3. Build Me Up, an Energy Pyramid! (10 points) Procedure: Use the following lists of organisms in building up an energy pyramid and place them in their proper trophic level. Copy the figure below to write the list of organisms. Then, write 3-4 sentences to explain the flow of energy in each trophic level in the ecosystem. trees Carrot Eagle snake rabbit grass

Energy Flow in Ecosystems Short Writing Activity Prompt: Use the model here to describe the transfer of matter and flow of energy from one trophic level to another within an ecosystem. All of the following must be addressed in your response to receive full credit: Discuss the transfer of biomass when one organism eats another. Use your knowledge of digestion to discuss how food is broken down and used by the consumer. Explain what happens to the energy that is not transferred from one organism to another. Explain why there are typically fewer organisms at the top of an energy pyramid. Use specific numbers and calculations to support your explanation.
